Helen Frobisher and Julie Wickham are turning sixty. They live in a small Dorset town and have been friends since school. On the surface Helen has it all - a lovely house and a long marriage to accountant Barry. Life has not been so kind to Julie, but now, with several failed businesses and bad marriages behind her, she has found stability: living in a council flat and working in an old people's home. Then Helen's world is ripped apart when Barry is found dead in a secret flat - or rather, a porn dungeon. It turns out Barry has been leading a fantastical double life as a swinger. He's run up a fortune in debts. The bank is going to take Helen's house and she'll lose everything she's never worked for.

Until, under the influence of an octogenarian gangster named Nails, the women decide that, rather than let the bank take the house, they're going to take the bank. With the help of several thrill-crazy, wheelchair-bound friends they pull off the daring robbery, but soon find that getting away with it is not so easy. Setting off across Europe, the team pick up a teenage hitchhiker, get entangled with Interpol and the Russian Mafia, and discover that, far from winding down, their lives are only just beginning. The Sunshine Cruise Company is a sharp satire on friendship, ageing, the English middle-classes, the housing bubble and group sex: Thelma and Louise meets the Lavender Hill Mob , written and directed by Tarantino.
